I forgot about the throttle setting. I just checked it, and the limit here is around 85 degrees, so I'll try again and get back to you.
The CPU will only reduce performance once it hits the 95°C threshold. I reached +83°C in prime95 with a 4.4GHz overclock. This setup uses a complete custom loop water cooling system and a cool day. Running at 103 watts seems improbable as well. I can run Cinebench between 60-65°C. After that, using aidia64 or prime95 will push it to 120 watts. Overall, it's not excessive in terms of power consumption (9900ks @ 5.2GHz is quite high, around 300 watts).

Most of the cooling is concentrated at the center of the IHS with my water block.
The upper boost frequency decreases as temperature rises and is unrelated to throttling. The CPU load also plays a role. AMD Ryzen performs more similarly to contemporary GPUs. In games that use the default core speed, limits are enforced. I can achieve all core boosts up to +4.424GHz, but with Cinebench (63c) and heavy tasks this value will decrease. For heavier workloads, 4.2–4.249GHz is typical. Video encoding tools like Prime95 or AIDA64 cause changes; enabling PBO and setting the scalar to x10 improves performance slightly. Aim for 4.2–4.3GHz. Reaching 95c triggers throttling to maintain temperature safety, which can be reduced in BIOS with PBO settings. You’ll fall below your usual boost speeds very quickly once this limit is hit. I haven’t reached 95c, but with suitable tasks I consistently achieve 80c+. For my 3800x, normal all-core clocks stay just above 4.2GHz at 80–85c [2].
I don't own a 3700X, yet Reddit users mentioned PC shutdowns at 95°C. Cooling reduces starts at 85°C, according to Lynton.
I consistently achieve 83-85c during prime95 small fft runs (fft 8k @ 4.4GHz 3800x) without throttling. I'm using the 3800x, though you'll notice a lower all-core clock speed under heavy loads by design. This remains true even if CPU temperatures rise.
VRM overheating can also trigger throttling and may lead to system shutdown if they reach limits. With my motherboard's VRMs being very robust, I don't experience overheating or throttling during a 4.45GHz all-core overclock. They rarely exceed 40c, averaging around 26c at the moment.
The main concern with the 3700x is its cooler is designed for a 65W TDP CPU, whereas the 3800x needs a cooler suited for a 105W TDP. Overclocking from 3700x to 3800x demands improved cooling. Some boards benefit from strong airflow around the VRMs.

Yea VRM heats up easily on low-end boards, which is why I use a motherboard with superior VRM. My current board crashes during Prime95 tests on anything above stock settings and causes PC shutdowns. I discovered helpful resources for VRM quality and overclocking on various motherboards: the first link and the second one.
I believe certain details you mentioned, like focusing on PBO, are actually aimed at boosting specific cores. My main goal here is all-core overclocking to take advantage of the x370's strengths without the newer chipsets' features (PBO2/XFR2). I’m confident I won’t lower my clock speeds to 4ghz for games like BFV, DeusExMD, FarCry5/NewDawn, or Division2. These higher core and thread counts are typical in modern game engines, so maximizing all-core performance helps avoid bottlenecks on the GPU. Regarding VRM, the ASRock Taichi provides excellent power delivery, which is why I chose it initially. The Corsair H80iV2 cooler is working well, and I wouldn’t expect much improvement with a triple cooler. Additional insights:

I’ve fine-tuned and feel settled at 1.425v CPU @4300mhz (disabling the 'offset' to 'auto') to maintain temperatures below 80°C. I’m using an LLC 3 core configuration, which is likely a safe setting on most boards. LLC 4 or 5 caused CinebenchR20 to fail, but my scores remain around 5000. The highest temperatures I’ve observed in gaming and benchmarking after long sessions are up to 79°C as reported by hwmonitor, so I’m confident there’s no throttling now. Also, I’m achieving solid FPS in games like Witcher3 1440p Ultra with the Vega VII, though performance drops noticeably when paired with paired GPUs. Thanks for your input.
The Taichi is among the top motherboards, easily upgrading to 3950X.
